2.yml

spring:
  application:
    name: xinguan-base-web

  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/xinguan?useUnicode=true&characterEncoding=UTF-8&serverTimezone=GMT%2B8
    username: root
    password: root
  jackson:
    date-format: yyyy-MM-dd HH:mm:ss
    time-zone: GMT+8

server:
  port: 8081

mybatis-plus:
  configuration:
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl   # 开启控制台 SQL 日志打印
  global-config:
    db-config:
      logic-delete-field: deleted  # 全局逻辑删除的实体字段名(since 3.3.0,配置后可以忽略不配置步骤2)
      logic-delete-value: 1 # 逻辑已删除值(默认为 1)
      logic-not-delete-value: 0 # 逻辑未删除值(默认为 0)
  mapper-locations: classpath*:/mapper/*.xml  # 用于将配置路径下的*.xml文件加载到mybatis中

3.启动类

@SpringBootApplication
@MapperScan("com.zhy.system.mapper")
//开启SwaggerUI
@EnableSwagger2
public class XinGuanApplication {
    public static void main(String[] args) {
        SpringApplication.run(XinGuanApplication.class,args);
    }
}

4.逆向生成

     * </p>
     */
    public static String scanner(String tip) {

            String ipt = scanner.next();
            if (StringUtils.isNotEmpty(ipt)) {
                return ipt;
            }
        }
        throw new MybatisPlusException("请输入正确的" + tip + "！");
    }

    public static void main(String[] args) {

        AutoGenerator mpg = new AutoGenerator();

        // 全局配置
        GlobalConfig gc = new GlobalConfig();
        gc.setOutputDir(scanner("请输入放置的子Moudle路径") + "/src/main/java");
        gc.setAuthor("zhy");
        //生成之后是否打开资源管理器
        gc.setOpen(false);
        //重新生成时是否覆盖文件
        gc.setFileOverride(false);
        //%s 为占位符
        //mp生成service层代码,默认接口名称第一个字母是有I
        gc.setServiceName("%sService");
        //设置主键生成策略  自动增长
        gc.setIdType(IdType.AUTO);
        //设置Date的类型   只使用 java.util.date 代替
        gc.setDateType(DateType.ONLY_DATE);
        //开启实体属性 Swagger2 注解
        gc.setSwagger2(true);
        mpg.setGlobalConfig(gc);

        dsc.setDbType(DbType.MYSQL);
        mpg.setDataSource(dsc);

        // 包配置
        PackageConfig pc = new PackageConfig();
        pc.setModuleName(scanner("请输入模块名"));

        pc.setServiceImpl("service.impl");
        pc.setMapper("mapper");
        pc.setEntity("entity");

        mpg.setPackageInfo(pc);

        // 策略配置
        StrategyConfig strategy = new StrategyConfig();

        strategy.setInclude(scanner("表名，多个英文逗号分割").split(","));

        //实体类名称驼峰命名
        strategy.setNaming(NamingStrategy.underline_to_camel);

        //列名名称驼峰命名
        strategy.setColumnNaming(NamingStrategy.underline_to_camel);
        //使用简化getter和setter
        strategy.setEntityLombokModel(true);
        //设置controller的api风格  使用RestController
        strategy.setRestControllerStyle(true);
        //驼峰转连字符
        strategy.setControllerMappingHyphenStyle(true);
        strategy.setTablePrefix("tb_");
        mpg.setStrategy(strategy);
        mpg.execute();
    }
